SAN JOSE, Calif., Dec. 5, 2017 /PRNewswire/ -- Pintail Power announced today a new patented technology that combines solar and conventional power generation with molten salt thermal energy storage to deliver low-carbon dispatchable power. The result is the production of more than ten times as much solar energy as in previous Integrated Solar Combined Cycle power plants, delivery of solar-generated energy, and Gigawatt-hour scale storage.

The new Dispatchable Solar Combined Cycle (DSCC) technology reduces fossil fuel use and green-house gases 30% below the world's most fuel efficient Combined Cycle Power Plant. As a unique and added benefit it provides more cost-effective energy storage to time shift solar energy into the evening, and permits faster startup and more responsive load following than conventional power plants.

Citing the CAISO Governors Vision for 2030 where base-load operation is replaced by flexible gas plants and energy storage, inventor and Pintail Power CEO William Conlon said, "This is the first of a new class of hybrid power systems designed to overcome the Duck Curve — essentially the challenge of PV solar over-generation during the day and the need for fast ramping energy to meet customer demand as the sun sets. DSCC increases the amount of solar energy delivered by 25% and reducing the cost of energy by 32%. Bottom line: customers benefit from a more efficient and more responsive system while significantly reducing the cost of energy."

The invention, U.S. Patent Number 9,816,490, will be offered by Pintail Power LLC, via technology licenses and design support to developers as a way to make CSP plants competitive in the US and expand global market opportunities, particularly in the Middle East and China.

About Pintail Power

Pintail Power, based in Palo Alto, California, is focused on delivering the benefits of hybrid energy storage to the power industry. Its goal is to cost-effectively reduce green-house gas emissions by time shifting renewables, thus avoiding curtailment and reducing fossil fuel use while maintaining reliability. The company also offers Liquid Air Power & Storage (LAPS) technology for re-powering combustion turbine peaker plants to increase capacity and efficiency thereby delivering technical, operational, and economic benefits to plant owners.
